RESUMO
Objective: To investigate the goal-oriented retroperitoneoscopic adrenalectomy and report the initial experiment. Methods: A total of 102 patients were selected to our clinic experiment, and performed retroperitoneoscopic adrenalectomy with the new method. including adrenal cortex adenoma 76 cases, phaochromocytoma 12 cases, adrenal cyst 6 cases, myelolipoma 4 cases, gangliocytoma 1 case and corticohyperplassia 3 cases. The mean diameter of the tumors was 2.8 cm (0.5-5.8 cm). The operative procedure was briefly described as such, with ultrasound guiding, a needle was punched percutaneously up to the adrenal mass or the renal upper pole from lateral to posterior axillary line just below the inferior border of the 12th rib. labeled the pathway of the needle with methylene blue. Along the way of the needle, a 12 mm port was introduced into the retroperitoneal space with closed method, and the laparoscope with a working tunnel was introduced to make a tunnel along the label up to the adrenal for finally removing it. Additional port should be used when it was needed in the procedure. Results: The procedures of all patients were successful, and 10 patients were performed with only one port, 81 patients with two ports, 11 patients with three ports. The operative duration was 49 (31-115) min, the average blood loss was 38 (0-260) ml. There was no transition to open surgery and no perioperative complications. The length of postoperative hospital stay was 4.1 d (2-7 d). 98 patients were available for follow-up of 16.5 months (1-38 months), no complication was found. Conclusions: The new method of retroperitoneoscopic adrenalectomy is feasible and safe for renal masses, and compared to the conventional method, it may be less trauma to the abdominal wall and retropertoneal tissue, and it was also better on cosmetics.
